Consistent with this result, Ca-EDTA did not delay the progression of Fura-6F signals during NMDA. Removal of extracellular Ca2+ reduced, but did not prevent FluoZin-3 increases. These results suggest that sustained Ca2+ increases indeed underlie Fura-6F signals that slowly propagate throughout neurons, and that Ca2+ (rather than Zn2+) increases are ultimately responsible for neuronal injury during NMDA. However, mobilization of Zn2+ from endogenous sources leads GSK2118436 solubility dmso to significant neuronal Zn2+

increases, that in turn contribute to mechanisms of initiation and progression of progressive Ca2+ deregulation. (C) 2009 IBRO. Published by Elsevier Ltd. All rights reserved.”
“Purpose: Platelet derived growth factor receptor inhibitor therapy improves the efficacy of taxane chemotherapy in preclinical models of prostate cancer. Men with high risk localized prostate cancer were treated with platelet derived growth factor receptor inhibitor therapy, docetaxel and hormone ablation in the preoperative setting, and clinicopathological outcomes were evaluated.

Materials and Methods: A total of 36 men with cT2 or greater disease, Gleason

grade 8-10, serum prostate specific antigen more than 20 ng/ml or cT2b and prostate specific antigen more than 1.0 ng/ml and Gleason 7 disease, without radiological evidence of metastases, were scheduled to Elafibranor concentration receive intramuscular leuprolide, 600 mg daily oral imatinib and 30 mg/m(2) weekly docetaxel X 4 every 42 days for 3 cycles before radical prostatectomy (beta [0.02, 1.98] prior on the possibility of pathological complete remission). Unresectable disease, postoperative prostate specific antigen 0.2 ng/ml or greater, or administration of postoperative selleck chemicals llc radiation or hormones were defined as treatment failure.

Results:

A total of 39 men were registered over 15 months. Median patient age was 57 years (range 44 to 71). Risk factors included T3 disease (22 of 39), Gleason 8-10 disease (31 of 39) and prostate specific antigen more than 20 ng/ml (12 of 39). Three men were ineligible or declined therapy, 29 of 36 (81%) received 3 cycles of therapy and 7 of 36 (19%) discontinued therapy related to toxicity. Grades 3-4 toxicity included rash (4), diarrhea (4), fatigue (6) and neutropenia (1). The surgical approach was feasible, without excessive or unusual complications such as wound dehiscence. No pathological complete remissions were defined. At a median followup of 39 months 53% were free from progression.

Conclusions: Evidence for a favorable impact of platelet derived growth factor receptor inhibitor therapy on the efficacy of neoadjuvant docetaxel and hormonal ablation in high risk localized prostate cancer was not obtained.”
“Cortical evoked response potentials (ERPs) display a rich set of waveforms that are both context and state dependent.

The nature of the shared liability differs by sex, and in males, by the type of tobacco product used. Differences between previous reports and results presented in the current study

“beta-Amyloid (A beta) peptides are derived from the sequential cleavage of the amyloid precursor protein (APP). They are enriched in plaques present in Alzheimer’s brains and thus play important roles in the pathogenesis of this disease. APP is also known to be expressed in the neurons of dorsal root ganglion (DRG) and contributes to neuronal survival and axonal growth during development. However, whether APP and A beta peptides are involved in nociception and pathological pain states is mostly unknown. In the present study, we have used behavioral, Tucidinostat research buy biochemical and morphological approaches to address this issue in both adult rats and APP over-expressing CRND8 transgenic mice. We observed that the A beta peptide (17-24) was predominantly expressed in small-sized DRG neurons of rats. Following intraplantar (i.pl.) injection of complete Freud’s adjuvant (CFA), the

levels of APP and A beta peptides were significantly reduced in the ipsilateral lumbar 4-6 rat DRG. In 3-, 12- and 24-month-old CRND8 mice, pain sensitivity in response to heat and mechanical stimulation was significantly dampened compared to their age-matched wild-type littermates. In parallel selleck with reduced pain sensitivity, the expression of pain mediators such as substance P, calcitonin gene-related peptide and transient receptor potential vanilloid-1 was significantly

reduced in L4-6 DRG of CRND8 mice. Although i.pl. injection of CFA induced a rather similar pattern of inflammatory pain in 3-month-old CRND8 mice and their wild-type littermates, recovery from inflammatory pain seemed faster in 12-month-old CRND8 mice than wild-type mice. These findings suggest that APP and A beta peptides suppress both nociception and inflammatory pain and are likely involved in blunt pain perception of Alzheimer’s patients in clinical settings.

“Purpose: The cost implications associated with offloading outpatient surgery from hospitals to ambulatory surgery centers and the physician office remain poorly defined. Therefore, we determined whether payments for outpatient surgery vary by location of care.

Materials and Methods: Using national Medicare claims from 1998 to 2006, we identified elderly patients who underwent 1 of 22 common outpatient urological procedures. For each procedure we measured all relevant payments (in United States dollars) made during the 30-day claims window that encompassed the procedure date. We then categorized payment types (hospital, physician and outpatient facility).

The molecular mechanisms underlying these environmentally induced developmental adaptations are unclear and best evaluated

in animal paradigms with translational salience. Rearing rat pups from to prevent social contact with conspecifics, produces reproducible, long-term weaning in PF-2341066 isolation, changes including; neophobia, impaired sensorimotor gating, aggression, cognitive rigidity, reduced prefrontal cortical volume and decreased cortical and hippocampal synaptic plasticity. These alterations are associated with hyperfunction of mesolimbic dopaminergic systems, enhanced presynaptic dopamine (DA) and serotonergic (5-HT) function in the nucleus accumbens (NAcc), hypofunction of mesocortical DA and attenuated 5-HT function in the prefrontal cortex and hippocampus. These behavioural, morphological and neurochemical abnormalities,

as reviewed herein, strongly resemble core features of schizophrenia. Therefore unravelling the mechanisms that trigger these sequelae will improve our knowledge of the aetiology of neurodevelopmental psychiatric disorders, enable identification of longitudinal biomarkers of dysfunction and permit predictive screening for novel compounds with potential antipsychotic efficacy.

“Since the free therapy program was started by the Thai government, the number of patients infected by HIV-1 with access to antiretroviral drugs has increased. The selection

of effective interpretation algorithms for antiretroviral drug resistance has become even more important for clinical management. In this retrospective study, the level of agreement was evaluated in 721 antiretroviral-therapy failing HIV-1 subjects. Regarding genetic diversity, about 89% was recognized as non-B variants (CRF01_AE). The level of complete concordant interpretation score in all seven algorithms was recognized in non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors selleck compound (PIs) (67%), but not in nucleoside reverse transcriptase inhibitors (NRTIs) (52%). Over 10% of the major discordance score with TRUGENE was revealed in didanosine (Agence Nationale de Recherches sur le SIDA[ANRS]; Detroit Medical Centre [DMC]), abacavir (ANRS; Centre Hospitalier de Luxembourg [CHL]), and also with delavirdine, indinavir and amprenavir (Grupo de Aconselhamento Virologico [GAV]). A good to excellent agreement range of kappa scores was detected for most antiretroviral drugs. However, poor agreement with the TRUGENE system (k < 0.40) was seen in the ANRS system with didanosine, abacavir and lopinavir; GAV system in indinavir and amprenavir; and DMC system in ritonavir. These might be an option for resource limited countries when selecting the use of a low cost or free algorithm interpretation, which has excellent agreement as the U.S.

CONCLUSIONS

MYO1E mutations are associated with childhood-onset, glucocorticoid-resistant focal segmental glomerulosclerosis. Our data provide evidence of a role of Myo1E in podocyte function and the consequent integrity of the glomerular filtration barrier.”
“Objective: The aim of this study was to determine the feasibility and durability of truly stentless aortic valve replacement using autologous pericardium sutured directly onto the aortic wall.

Methods: Eleven patients (mean age, 55.9 years) requiring aortic valve replacement were recruited. A circular piece of pericardium about 8 cm in diameter was harvested

and treated in 0.6% glutaraldehyde for 10 minutes. The aortic valve was excised and, with the use of specially designed instruments (CardioMend LLC, GW786034 Santa Barbara, Calif), the sinotubular junction was sized and the pericardium was tailored to the required size and shape and then sutured directly onto the aortic wall. The reconstructed valve was assessed directly and by echocardiography at the end of the operation; it was assessed by echocardiography and cardiac magnetic resonance imaging at 6 months and yearly. Computed tomographic scan of the aortic valve to assess for valve calcification was performed at last follow-up.

Results: Hospital mortality was 0%. Mean follow-up was 6.5 years (range, 5.3-7.5 years). Freedom from structural valve

deterioration, thromboembolism, endocarditis and reoperation was 100%, 100%, 72.7%, and 63.6%, respectively. There were 4 reoperations at 4, 13, 15, and 46 months, 3 of them owing to endocarditis and 1 owing to SHP099 mw technical failure noted at the time of surgery. The remaining 7 patients are alive and well with a mean New York Heart Association class of 1.3 and normally functioning aortic valves with no calcification.

Conclusions: Truly stentless aortic valve replacement using autologous pericardium sutured directly onto the aortic wall is safe and feasible and has excellent durability up to 7.5 years with no calcification. (J Thorac Cardiovasc Surg 2011;141:276-83)”
“BACKGROUND

Dupuytren’s

disease is a benign fibromatosis of the hands and fingers that leads to flexion contractures. We hypothesized that multiple genetic and environmental factors influence Proteases inhibitor susceptibility to this disease and sought to identify susceptibility genes to better understand its pathogenesis.

METHODS

We conducted a genomewide association study of 960 Dutch persons with Dupuytren’s disease and 3117 controls (the discovery set) to test for association between the disease and genetic markers. We tested the 35 single-nucleotide polymorphisms (SNPs) most strongly associated with Dupuytren’s disease (P< 1×10-4) in the discovery set in three additional, independent case series comprising a total of 1365 affected persons and 8445 controls from Germany, the United Kingdom, and the Netherlands.

RESULTS

Initially, we observed a significant genomewide association between Dupuytren’s disease and 8 SNPs at three loci.

Recent studies have indicated that the contribution of specific ion channels to these hallmarks varies for different types of cancer. Therefore, to determine the importance of ion channels as targets for cancer diagnosis and treatment their expression, function and regulation must be assessed for each cancer.”
“Background: Endovascular aneurysm repair (EVAR) is associated with an improved perioperative mortality compared to open surgical repair. This benefit may reflect reduced incidence of microvascular and macrovascular thrombotic complications after EVAR.

Purpose: The purpose of this study was to review and compare the effects of abdominal aortic aneurysm (AAA), open

surgical repair, and EVAR on coagulation, fibrinolysis, LY2090314 cell line and platelet activation.

Methods: A MEDLINE (1966-2010) and Cochrane library search for articles relating to the effects of AAA, open surgical repair, and EVAR on hemostasis was performed utilizing and cross-linking terms such as clotting, fibrinolysis, AAA, EVAR, and open VE 821 surgical repair. Studies with a small cohort of patients (less than 7) or in which values of assessed biomarkers were not included were rejected.

Results: AAA is associated with increased thrombin generation,

activity, and fibrin turnover as evidenced by increased plasma levels of thrombin-antithrombin III-complex (TAT), activated protein C-protein C inhibitor (APC-PCI), fibrin-monomer-fibrinogen (FM-F), F1+2, fibrinogen, and D-dimer. The extent of hemostatic derangement correlates with the volume of intraluminal thrombus. This procoagulant

state is exaggerated in the immediate perioperative period after both open surgical repair and EVAR, but is attenuated at medium-term follow-up although not normalized.

Conclusion: The resultant prothrombotic diathesis after open surgical repair and EVAR may account for the high level of perioperative thrombotic complications. (J Vasc Surg 2011;54:865-78.)”
“Escherichia coli is widely employed to produce recombinant proteins because this microorganism is simple to manipulate, inexpensive to culture, and of short duration to produce a recombinant protein. However, contamination of molecular chaperone DnaK during purification of the recombinant protein is Momelotinib cell line sometimes a problem, since DnaK sometimes has a negative effect on subsequent experiments. Previously, several efforts have been done to remove the DnaK contaminants by several sequential chromatography or washing with some expensive chemicals such as ATP. Here, we developed a simple and inexpensive method to express and purify recombinant proteins based on an E coli dnaK-deletion mutant. The E. coli Delta dnaK52 mutant was infected by lambda DE3 phage to overexpress desired recombinant proteins under the control of T7 promoter.

In addressing various discrepancies, we hypothesized that cells in the chorioamniotic mesodermal layer have plasticity. Immunophenotyping of these cells using a panel of antibodies (CD14, CD68, CD163, HLA-DR, type I procollagen, a-smooth www.selleckchem.com/products/PHA-739358(Danusertib).html muscle actin, desmin, vimentin) revealed coexpression of both myofibroblast and macrophage markers. The proportion of CD14+ macrophages was higher in inflamed chorioamniotic membranes (P<0.05). Cells immunoreactive to the macrophage markers showed nuclear expression of PU.1, a hematopoietic cell-specific transcription factor. Furthermore, treatment with proinflammatory

cytokines (IL-1 beta and TNF alpha) or Toll-like receptor-4 overexpression upregulated PU.1 mRNA expression in chorioamniotic mesodermal cells. Overexpression of PU.1 in chorionic mesodermal cells increased the expression of CD14 mRNA and protein. A reporter gene assay

and chromatin immunoprecipitation demonstrated binding of PU.1 to the CD14 promoter region. This study reports that chorioamniotic mesodermal cells display plasticity ranging from overt transformation of fibroblast/myofibroblast to macrophages, and that PU.1 plays a role in macrophage differentiation. Chorioamniotic mesodermal cells are another novel example of phenotypic switching between fibroblast/myofibroblast and macrophage. The findings reported herein suggest that the plasticity of mesodermal BMS-754807 nmr cells is an effective mechanism of the chorioamniotic membranes to manage several biological needs, click here such as mucosal immune defense and the maintenance/disruption of physical

integrity, with a limited pool of cells.”
“Introduction: Non carrier added (NCA) 2-[F-18]fluoromethyl-L-phenylalanine is currently used in a Phase I study. Improvement of the stability of the fluorobenzyl analogue, very sensitive to defluorination and hydrolysis, during the synthetic route and in the radiopharmaceutical formulation was devised.

Methods: The protected brominated precursor was synthesised in three steps. The labelling with [F-18(-)]occurred in acetonitrile using K2CO3/K-2.2.2 (120 degrees C, 5 min). NCA 3-(2-[F-18(-)]Fluoromethyl-phenyl)-2-tert-butoxycarbonylamino-propionic acid tert-butyl ester recovered from HPLC was submitted to deprotection in TFA/CH2Cl2 in the presence of CaCl2. After evaporation and adsorption on a mini C18 column, the tracer was recovered in 4 ml of H2O. Appropriate amounts of CaCl2 and NaCl solutions were added for isotonic formulation, and this solution was sterilised by a 0.2-mu m Cathivex filter. Shelf-life stability in the presence of Ca2+ and Mg2+ ions was studied. Stereoisomeric purity was checked by chiral HPLC.

Results: The labelling showed a reproducible labelling yield of at least 90%.

012). Patients with chromophobe renal cell carcinoma were more likely to have metastasis to the liver compared to those with clear cell renal cell carcinoma (33.3% vs 9.7%, p = 0.007), but there was not a statistically significantly difference in the incidence of liver metastases between patients with chromophobe and papillary renal cell carcinoma (33.3% vs 18.0%, p Cisplatin ic50 = 0.308).

Conclusions: Site of distant metastasis varies significantly by renal cell carcinoma histological subtype. Patients with clear cell

renal cell carcinoma are more likely to have metastasis to the lungs while patients with chromophobe renal cell carcinoma are more likely to experience liver metastasis.”
“Introduction Dynamic perfusion-CT (PCT) with deconvolution requires an arterial input function (AIF) for postprocessing. In clinical settings, the anterior cerebral artery (ACA) is often chosen for simplicity. The goals of this study were to determine how the AIF selection JSH-23 cell line influences PCT results in acute stroke patients and whether the ACA is an appropriate default AIF.

Methods We retrospectively identified consecutive patients suspected of hemispheric stroke of less than 48 h duration who were evaluated on admission by PCT. PCT datasets were

postprocessed using multiple AIF, and cerebral blood volume (CBV) and flow (CBF), and mean transit time (MTT) values were measured in the corresponding territories. Results from corresponding territories in the same patients were compared using paired t-tests. The volumes of infarct core and tissue at risk obtained with different AIFs were compared to the final infarct volume.

Results Of 113 patients who met the inclusion criteria, 55 with stroke were considered for analysis. The MTT values obtained with an “”ischemic”" AIF tended to be shorter (P=0.055) and the CBF values higher (P=0.108) than those obtained using a “”nonischemic”" AIF. CBV values were not influenced by the selection of the AIF. No statistically significant difference was observed between the size of the PCT infarct whatever core (P=0.121) and tissue at risk (P=0.178),

regardless of AIF selection.

Conclusion In acute stroke patients, the selection of the AIF has no statistically significant impact of the PCT results; standardization of the PCT postprocessing using the ACA as the default AIF is adequate.”
“Introduction Aneurysms of the posterior cerebral artery (PCA) are rare, and most of the studies reported in the literature in which the endovascular approach was applied were carried out on a limited number of patients with PCA aneurysms. We retrospectively reviewed our cases of PCA aneurysms – at various locations and of differing shapes – that received endovascular treatment and evaluated the treatment outcome.

Methods From January 1996 to December 2006, 13 patients (eight females and five males) with 17 PCA aneurysms (nine fusiform and eight saccular) were treated using the endovascular approach.

“Polyunsaturated fatty acids (PUFAs) can be classified in n-3 fatty acids and n-6 fatty acids, and in westernized diet the predominant dietary PUFAs are n-6 fatty acids. Both types of fatty acids are precursors of

signaling molecules with opposing effects, that modulate membrane microdomain composition, receptor signaling and gene expression. The predominant n-6 fatty acid is arachidonic acid, which is converted to prostaglandins, leukotrienes and other lipoxygenase or cyclooxygenase products. These products are important regulators of cellular functions with inflammatory, atherogenic and prothrombotic effects. Typical n-3 fatty acids are docosahexaenoic acid and eicosapentaenoic Selleck Sotrastaurin acid, which are competitive substrates for the enzymes and products of arachidonic acid metabolism. Docosahexaenoic Gamma-secretase inhibitor acid- and eicosapentaenoic acid-derived eicosanoids antagonize the pro-inflammatory effects of n-6 fatty acids. n-3 and n-6 fatty acids are ligands/modulators for the nuclear receptors NF kappa B, PPAR and SREBP-1c, which control various genes of inflammatory signaling and lipid metabolism. n-3 Fatty acids down-regulate inflammatory

genes and lipid synthesis, and stimulate fatty acid degradation. In addition, the n-3/n-6 PUFA content of cell and organelle membranes, as well as membrane microdomains strongly influences membrane function and numerous cellular processes such as cell death and survival.

“A one-step multiplex IWP-2 order RT-PCR method using new primers was developed

for the simultaneous detection and differentiation of Vietnamese FMDV serotypes O, A, and Asia 1 directly from clinical samples. The RT-PCR method used a cocktail of one universal minus-sense primer designed in the 2B gene and three serotype-specific plus-sense primers designed in the hypervariable regions of the capsid VP1 coding gene of FMDV. These serotype-specific primer pairs amplified 658, 535, and 427 bp PCR products corresponding to FMDV serotypes O, Asia 1, and A, respectively. In this study, six well-characterized FMDV strains belonging to serotypes O,A, and Asia 1 were used as reference strains for validation tests. Among these six FMDV strains were three vaccine strains for type O (O1/Manisa), A (A22/Iraq), and Asia 1 (As1 /Shamir/89). The other reference strains included one pandemic strain of FMDV serotype Asia 1 (Asia1 /MOG/05) and two pandemic strains of FMDV serotype O (O/UKG/34/2001 and O/SKR/2000). For field application, 37 positive-clinical samples and 18 cell culture-adapted viruses belonging to serotypes O, A, and Asia 1, as confirmed previously by antigen ELISA for FMDV detection, were used. The present method showed high sensitivity and specificity and can be adapted for detection and typing of FMDV serotypes O. A, and Asia 1 circulating in Vietnam. (C) 2011 Elsevier B.V.

arachidonic acid (AA) seems characterized by both synergism and antagonism.

Materials and methods: Investigate the relation between EPA + DHA and AA in populations with a wide range of EPA + DHA status and across the life cycle. EPA + DHA and AA were determined in erythrocytes (RBC; n=1979),

umbilical arteries (UA; n=789) and umbilical veins (UV; n=785).

Results: In all compartments, notably RBC, the relation between EPA + DHA and AA appeared bell-shaped. Populations with low RBC-EPA + DHA ( Cisplatin <2 g%) exhibited positive relationships; those with high RBC-EPA+DHA ( > 8 g%) negative relationships. Antagonism in UA and UV could not be demonstrated.

Conclusion: Both synergism and antagonism might aim at a balance between omega 6 and omega 3 long-chain polyunsaturated fatty acid (LCP) to maintain homeostasis. Synergism might be a feature of low LCP omega 3 status. AA becomes suppressed by antagonism from an RBC-EPA+DHA > 8 g%. (C) 2011 Elsevier Ltd. All rights reserved.”
“The treatment of hyponatremia, an exceedingly common electrolyte disorder, has been a subject of controversy for many years. The advent of vasopressin antagonists (vaptans) has

added to the treatment arsenal. This review focuses on why hyponatremia should be treated and the role of these antagonists in the treatment. Upon analysis of the available literature, we conclude H 89 cost that there is presently no role for vaptans in acute symptomatic hyponatremia. Although numerous therapeutic approaches are available for chronic symptomatic hyponatremia, vasopressin antagonists provide a simpler treatment option. Vaptans WH-4-023 supplier are efficacious in raising serum sodium in long-standing ‘asymptomatic’ hyponatremia. However, the cost of the only Food and Drug Administration-approved oral agent (tolvaptan) makes its use prohibitive for most patients in this setting.

“We have previously reported that essential fatty acid deficiency (EFAD) during suckling in mice resulted in an adult lean phenotype

and a resistance to diet-induced obesity. We now hypothesized that postnatal EFAD would cause long-term effects on lipid metabolism. C57BL/6 mice were fed an EFAD or a control diet from the 16th day of gestation and throughout lactation. The pups were weaned to standard diet (STD) and at 15 weeks of age given either high fat diet (HFD) or STD. Lipoprotein profiles, hepatic lipids, fatty acids and mRNA expression were analyzed in 3-week-old and 25-week-old offspring. At weaning, the EFAD pups had higher cholesterol levels in both plasma and liver and 6-fold higher concentrations of hepatic cholesterol esters than control pups. Adult EFAD offspring had higher levels of hepatic cholesterol and linoleic acid, but lower levels of dihomo-gamma-linolenic acid and Pparg mRNA expression in the liver.

Two patients with chordoma relapsed; 1 died of disease, and the other was alive with disease. Two patients with metastasis died of multiple remote metastases. No evidence of local recurrence was found in the other patients.

CONCLUSION: The anterior retropharyngeal approach is a favorable route to treat tumor lesions of the C2 vertebral body that allows tumor resection and placement of anterior constructs PLX-4720 price between C1 and the subaxial vertebral body. Tumor resection and 2-column reconstruction could safely be accomplished simultaneously through the combined

“Stroke is a common, serious, and disabling global health-care problem, and rehabilitation is a major part of patient care. There is evidence to support rehabilitation

in well coordinated multidisciplinary stroke units or through provision of early supported provision of discharge teams. Potentially beneficial treatment options for motor recovery of the arm include constraint-induced movement therapy and robotics. Promising interventions that could be beneficial to improve aspects of gait include fitness training, high-intensity therapy, and repetitive-task training. Repetitive-task training might also improve transfer functions. Occupational therapy can improve activities of daily living; however, information about the clinical effect of FG-4592 datasheet various strategies of cognitive rehabilitation and strategies for aphasia and dysarthria is scarce.

“BACKGROUND: Supra find more orbital frontal minicraniotomy is one of the most commonly used minimally invasive approaches for anterior cranial fossa lesions.

OBJECTIVE: To describe our experience with the transpalpebral “”eyelid”" incision to obtain access to the anterior cranial fossa.

METHODS: We describe the approach and technique of the transpalpebral eyelid incision in a step-by-step fashion and discuss the results of 40 cases for which the eyelid incision was used. We retrospectively reviewed the charts of these patients to analyze outcomes with regard to opening and closing time, length of hospital stay, residual aneurysm or Simpson grade for resection, complications, and cosmetic result.

RESULTS: We treated 31 anterior circulation aneurysms (28 unruptured and 3 ruptured), 7 anterior skull base meningiomas, 1 frontal low-grade glioma, and 1 frontal cavernoma using the transpalpebral incision. Opening time was about 45 to 60 minutes, and closure time from dura to skin was about 45 to 60 minutes. The hospital length of stay was similar to that in our open craniotomy cases. No residual aneurysm was demonstrated in the follow-up studies of all 31 aneurysms. Simpson grade I resection was achieved in 6 meningiomas.
